IPC: H01J9/02
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To print a uniform printing pattern on a printed substrate by providing a plurality of projecting regions that can hold an edge shape of the tip of a scraper and a cross sectional shape of a screen plate in the substantially same form, in a view from a scraper's progressing direction, by abutting the lower surface of the screen plate. SOLUTION: This substrate 2 is fixed to a printing stage 6 so that a bump 1 does not overlap on a position of a printing pattern to be printed on a printed substrate. Next, an interval between a screen plate and the substrate 2 is set 0.5 mm. Then, a scraper 7 is lifted down onto the upper surface of a screen 4, and is moved in parallel on the screen 4. By bringing the central part and both ends of the lower surface of the screen 4, the surface of the screen 4 in a region where a pattern 11 corresponding to a line of a cutting edge of the scraper 7 is held in a substantially parallel relation. Thus, printing paste 8 developed in the region having the pattern 11 of the screen 4 is developed in a uniform thickness.

Abstract: PURPOSE:To remove phosphoric ion from waste water at a low cost, by stripping waste water containing phosphoric ion, and bringing it into contact with the crystal seeds of calcium phosphate in the presence of Ca. CONSTITUTION:Phosphate-contg. raw water 11, e.g. treated water of night soil, sewage or industrial waste water, is adjusted to a pH of 3-5 by the addition of an acid 13 such as sulfuric acid. Said raw water is introduced into a decarboxylation column 15 and stripped therein by releasing air from a lower side. CO2- contg. stripping gas is discharged through a line 17, while the decarboxylated raw water is withdrawn through a line 19. Said raw water is adjusted to a pH above 6 by the addition of an alkaline Ca agent 21 such as slaked lime. Thereafter, the raw water is sent into a crystallization dephosphorizer column 23 and brought into contact with crystal seeds containing calcium phosphate, e.g. hydroxyapatite, fluoroapatite or trilime phosphate, charged in the column to crystallizedly dephosphorize phosphoric ion as calcium phosphate on the surfaces of said crystal seeds. The dephosphorized raw water is introduced into a neutralizer column 27, neutralized therein with the stripping gas 17 and then drained.

IPC: G06F3/041
Filed: 1983-03-26
Abstract: PURPOSE:To simplify the structure and at the same time to facilitate an input operation with a titled input device by putting two pairs of polymer piezoelectric films subjected to uniaxial orientation and polarization processing on each other with their orienting directions set orthogonal to each other and with a small gap secured between them. CONSTITUTION:Polymer piezoelectric films 1 and 2 have transparent areas through which a display screen 4 is viewed, and the orienting directions 13 and 14 of these two films are orthogonal to each other at fixed parts 5 and 7 as well as 6 and 8. Small gaps are secured between films 1 and 2 as well as between the film 1 and a transparent substrate 3 respectively. Then spacers 5'-8' are put into these gaps to avoid mutual contacts among those films and substrate unless they are pressed with fingers, etc. Thus the films 1 and 2 can form planes with sufficient tension. The AC power given from an oscillator 16 is converted into mechanical vibrations through electrical/mechanical converters 9 and 10. These mechanical vibrations are transmitted into the films 1 and 2 in their orienting directions as longitudinal waves and then converted into electric signals by pickups 11a-11h and 12a-12h respectively.

Abstract: PURPOSE:To facilitate the commodity replenishing operation by a simple constitution and to improve the reliability by returning automatically a guide plate to a holding position with a spring at the time when the commodity replenishment is completed. CONSTITUTION:A guide plate 16 holds the front of a commodity laminated on a containing frame 7 by the tip part, and prevents the commodity from jumping out. At the time of replenishing the commodity, when it is tried to contain the commodity from the front of the containing frame 7, the guide plate 16 is pressed in the inserting direction of the commodity, the guide plate 16 turns to the inside against energizing force of a torsion spring 17 by using a guide lever 15 as an axis, and the commodity can be inserted into the containing frame 7. After the commodity replenishment is completed, the guide plate 16 is released as to its pressure from the commodity, therefore, it turns automatically until the guide plate 16 abuts on a projecting part 14b of an adjusting piece by energizing force of the spring 17, and is controlled. Accordingly, the commodity replenishing operation can be executed easily by a simple constitution, and the reliability is improved.

Abstract: PURPOSE:To enable a wide range of utilization of the device by a method wherein the movement in the axial direction of a float with a magnet indicating a level of liquid moves vertically is converted into a rotational change by a magnetic rotary plate and further the rotation is detected by a magnetism-resisting element. CONSTITUTION:A magnet 2 is provided in the float 1 moving vertically indicating the level of liquid moves vertically and this magnet 2 is connected magnetically with the plane-shaped rotary plate made rotatably by supporting shafts 5 and 6 inside a cylindrical nonmagnetic enclosing apparatus 3. Moreover, in the range of an angle of 90 deg. on the outer-peripheral surface of the enclosing apparatus 3, a guiding projection 9 projected vertically in a spiral form is fitted freely to the groove of the inner- peripheral surface of the float 1. By such a constitution, the float 1 rotates in the range of 90 deg. and with this the rotary plate also rotates when the float 1 moves vertically  with the vertical movement of the level of liquid. Therefore, when this rotation is found as the change in a resistance value by the magnetism-resisting element 8 which is provided at the tip of the supporting shaft 5 of the rotary plate 5 for detecting the magnetic change of a magnet 7, the level of the liquid can be measured.
